THREAD-CUTTING LOOlVl-TEMPLE.

SPECIFICATION forming part of Letters Patent No. 766,501, dated August2, 1904,

Application filed May 26, 1904:. Serial No. 209,831- (No model.

To all whom it 77mg concern.-

Be it known that I, ALFRED A. HULL, a citizen of the United States, anda resident of Knoxville, county of Knox, State of Tonnessee, haveinvented an Improvement in Thread- Outting Loom-Temples, of which thefollowing description, in connection with the accompanying drawings, isa specification, like charaeters on the drawings representing likeparts.

This invention has for its object the production of a thread-cuttingloom-temple embodying certain novel features of construction whereby avery positive and certain cutting action on the thread is insured, thetemple relating to the type forming the subject-matter of United StatesPatent No. 585,465. In the temple shown therein the head is slottedtransversely at its outer end to receive an upright fixed blade and acooperating movable blade, the outer end of the latter being bifurcatedor slotted to receive the fixed blade, and the movable blade is alsodownturned or hooked at its outer end. \Vhen the thread is to besevered, the said blade is depressed to cause its hooked end to engagethe thread, and then the blade is drawn into the head, thereby pullingthe thread against the fixed blade to part it, the parting or severanceof the thread partaking more of a break than a clean cut. The movableblade is actuated by or through the movement of the lay, and thevibration of the loom and slight changes in the stroke of to thoseskilled in weaving) sometimes will fail to eli'ect the severance of thethread as by the movable blade being insufiicient to break it across thefixed blade.

In my present invention 1 have devised means to positively cut thethread by a shearlike action,-the movable cutting-blade being yieldinglypressed against a relatively fixed plate, so that when the cutting-bladeengages the thread the cutting edge of such blade is drawn across thethread with a shearing movement, the edge of the fixed plate presentingthe resistance necessary to maintain the thread in position to besheared. The cutting action is thus made certain and a sharp clean cutis made promptly and quickly and uninfluenced by loom vibrations orvariations in the laystrokes.

The novel'features of my invention will be fully described in thesubjoined specification, and particularly pointed out in the followingclaims.

Figure 1 is an inner side elevation of a threml-cutting loom-templeembodying my present invention. Fig. 2 is an outer side view thereof,the temple-stand being broken off. Fig. 3 is an end elevation of thetemplehead and adjacent parts, and Fig. 4: is a top or plan viewthereof.

The stand A, the head comprising the pod B, cap B, the heel B, attachedto the pod, and the toothed roll B rotatable on pivots carried by thecap, are in their general construction and arrangement substantially asin the patent referred to. The pod is slotted at 1, Fig. 3, to receivethe lower end of an upright metallic plate 2,, preferably of steel andheld fixedly in position by a screw 3, the upper end of the plateextending into the open end of a transverse slot& in the pod, the plate2 and slot being shown in dotted lines, Fig. 4. The shank B, whichcarries the temple-head, has a lateral enlargement I) slotted incontinuation of the slot L, and the cutting-blade 5 is inserted in theslots, the outer end of the blade being downturned or hooked, as at 6,and normally projecting beyond the outer end of the slot 4:, as shown.

A cutting edge 7, Figs. 1 and 2, is formed on the outer end of the bladeat its under side, said blade being pressed against the side of theplate 2 by a spring 8, rigidly attached by a suitable screw 9, Fig. 1,to the inner side of the shank B, the free end of the spring bearingagainst the blade 5 behind the pod and cap, as shown.

A wire spring 10, spirally coiled at 11 to lit over a stud 12 on theshank B, has one end 13 bearing against a shoulder 1a thereon, theopposite end of the spring being downturned and bent into a loop 15,fitted over a lateral lug 16 on the heel 17 of the blade 5, allsubstantially as in said Patent N o. 585A65, the spring normallyprojecting the blade,as shown in the drawings.

The lateral enlargement 18 at the inner end of theblade acts to limitits spring-induced movement, a shoev 19, Fig. 2, on the blade sliding onthe beveled under side 20 of the ear 6 to permit the shoe to slide androck when the cutting-blade is operated.

As the lay beats up it first strikes the heel 17 of the blade 5 andimmediately rocks the latter, depressing the hooked end 6 thereof, itscutting edge 7 wiping past the adjacent upright corner of the plate 2,and as the lay completes its movement the blade is drawn into thetemple-head. If there is at such time a filling end between the selvageand the shuttle, such filling end will be caught by the hooked end ofthe blade 5 and drawn up against the plate 2 to be positioned thereby,and the cutting edge 7 by continued inward movement of the blade 5 drawsacross and shears or cuts the filling cleanly and sharply with an actionsimilar to that of a pair of scissors or shears. The cut is made by thedrawing action of the edge 7 across the filling instead of by pullingthe filling across a fixed member till it breaks, and as the drawingaction of the cutting edge is effected by engagement of the lay and theheel 17 it is not influenced improperly by vibration of the loom or avariation in the lay-stroke. The shearing nature of the cut ismaintained by the spring 8, which always presses the cutting edge of theblade 5 against the side of the fixed plate 2, so that the filling isfirmly supported immediately adjacent the cutting-point.

It is to be understood that the stand A will be provided with a suitablespring (not shown) to push the temple-head toward the back of the loom,the lay when beating up forcing the temple-head forward, as is common inreciprocating temples.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A temple-head provided with a toothed roll and having a transverseslot at its outer end, a movable blade located in the slot and having acutting edge, a fixed support or stop for the filling-thread, extendingupward in the slot, a spring to press the blade against the side of thesaid support, and means to operate the blade and draw its cutting edgewith a shearing action past the support.

2. A temple-head provided with a toothed roll and having a transverseslot at its outer end, an upright plate fixedly mounted within the slot,a movable blade located in the slot and having a cutting edge, a springto press said blade against the side of the plate, and means to operatethe blade and draw its cutting edge with a shearing action pastthe frontedge of the plate.

3. A temple-head provided with a toothed roll and having a transverseslot at its outer end, an upright plate fixedly mounted within the slot,a movable blade located in the slot and having a downturned hooked endnormally projecting beyond the temple-head and provided on its underside with acutting edge, a spring to yieldingly press the blade againstthe side of the plate, and means to retract the blade and cause itscutting edge to wipe past the adjacent front corner of the plate.

t. In a loom-temple, a pod, a cap having a transverse slot at its outerend, an upright plate fixedly mounted in the slot, a movable bladehaving a downturned, hooked outer end provided on its under side with acutting edge, a spring in sliding engagement with and serving to pressthe blade against the side of the plate, and means to operate the bladeto cut with a shearing cut a filling end interposed between the frontedge of the plate and the cutting edge of the blade.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALFRED A. HULL.
